Milestone for novel atomic clock      (via sciencedaily.com)     Original source 

An international research team has taken a decisive step toward a new generation of atomic clocks. The researchers have created a much more precise pulse generator based on the element scandium, which enables an accuracy of one second in 300 billion years -- that is about a thousand times more precise than the current standard atomic clock based on caesium.

Researchers discover disease-causing stem cells in lungs of cystic fibrosis patients      (via sciencedaily.com)     Original source 

Experts in cloning and stem cell science are reporting that five lung stem cell variants dominate the lungs of patients with advanced cystic fibrosis, and that these variants drive key aspects of CF pathology including inflammation, fibrosis and mucin secretion.

A close-up of biological nanomachines: Researchers take a deep look at peroxisomal processes      (via sciencedaily.com) 

The cell organelles known as 'peroxisomes' dispose toxic substances and fats in the human body, among other things, and, in doing so, they prevent serious illnesses. The 'Pex' group of proteins (peroxisomes biogenesis factors) keep these 'detox units' functioning properly -- and now researchers have shown, at the atomic level, how these highly complex processes proceed.

Double trouble: Infamous 'eagle killer' bacterium produces not one, but two toxins      (via sciencedaily.com)     Original source 

The cyanobacterium Aetokthonos hydrillicola produces not just one, but two highly potent toxins. Scientists describe the second toxin, which had remained elusive until now. Even in low concentrations, it can destroy cells and is similar to substances currently used in cancer treatment. Two years ago, the same team established that the first toxin from the cyanobacterium is the cause of a mysterious disease among bald eagles in the USA.

Did life exist on Mars? Other planets? With AI's help, we may know soon      (via sciencedaily.com)     Original source 

Scientists have discovered a simple and reliable test for signs of past or present life on other planets -- 'the holy grail of astrobiology.' Researchers report that, with 90% accuracy, their artificial intelligence-based method distinguished modern and ancient biological samples from those of abiotic origin.

New research adds evidence to the benefits of ginger supplements for treating autoimmune diseases      (via sciencedaily.com)     Original source 

New research has revealed a potentially important role ginger supplements can play in controlling inflammation for people living with autoimmune diseases. The research focused on studying the impact of ginger supplementation on a type of white blood cell called the neutrophil. The study was especially interested in neutrophil extracellular trap (NET) formation, also known as NETosis, and what it may mean for controlling inflammation. The study found ginger consumption by healthy individuals makes their neutrophils more resistant to NETosis. This is important because NETs are microscopic spider web-like structures that propel inflammation and clotting, which contribute to many autoimmune diseases, including lupus, antiphospholipid syndrome and rheumatoid arthritis.

Same genes behind heart muscle disorders in humans and Dobermanns      (via sciencedaily.com)     Original source 

Researchers have made a significant finding in determining the genetic background of dilated cardiomyopathy in Dobermanns. This research helps us understand the genetic risk factors related to fatal diseases of the heart muscle and the mechanisms underlying the disease, and offers new tools for their prevention.

This parasitic plant convinces hosts to grow into its own flesh--it's also an extreme example of genome shrinkage      (via sciencedaily.com)     Original source 

Balanophora shed one third of its genes as it evolved into a streamlined parasitic plant -- an extreme degree of genome shrinkage even among parasites. Along the way this subtropical plant developed the ability to induce the host plant to grow into the parasite's own flesh -- forming chimeric organs that mix host and parasite tissues.

Researchers develop first method to study microRNA activity in single cells      (via sciencedaily.com) 

Researchers have developed the first method to uncover the tasks that microRNAs perform in single cells. This is a huge improvement over existing state-of-the-art methods that require millions of cells and will for the first time allow researchers to study microRNAs in complex tissues such as brains.

Nanoparticles made from plant viruses could be farmers' new ally in pest control      (via sciencedaily.com) 

Engineers have devised a new solution to control a major agricultural menace, root-damaging nematodes. Using plant viruses, the researchers created nanoparticles that can deliver pesticide molecules to previously inaccessible depths in the soil. This 'precision farming' approach could potentially minimize environmental toxicity and cut costs for farmers.
